The mean ejection fraction of the population as a whole was52.2 +/- 13. In 10.5% of the cases there was severe left ventricular (LV)function impairment with a mean ejection fraction (EF) of 30.2 +/- 4.4(range 20-35). A major preoperative complication occurred in 8.2% of theentire population and 68.8% of the patients undergoing emergency surgery.Surgery was elective in 72.7% of the cases, urgent in 15.4% and emergencyin 11.9%. Hospital mortality was 4.1% (CL 3.2-4.9). In the group ofelectively operated patients, mortality was 2.7% (CL 1.8-3.5), with nostatistically significant difference (P = 0.943) from the mortalityobserved in the patients undergoing urgent surgery [2.5% (CL 0.8-4.1)]. Themortality in both groups was statistically different (P = 0.0001 and P =0.008) from that of the patients undergoing emergency surgery [14.7% (CL10.1-18.9)]. Perioperative acute myocardial infarction occurred in 5.4% ofthe patients (CL 4.4-6.4), in three cases resulting in death [10.7% (CL4.8- 15.8)]. Fourteen of the acute myocardial infarctions (AMI) occurred inthe 42 patients undergoing emergency surgery for acute coronary occlusion(33.3%). A percentage of 18.7% of the 493 surviving patients suffered apostoperative complication.(ABSTRACT TRUNCATED AT 250 WORDS) European Journal of Cardio-Thoracic Surgery Elsevier Science B.V. 9/5(1995-05), 275-282 1010-7940 9:5<275 1995 9 ejcts https://doi.org/10.1016/S1010-7940(05)80162-9 text/html Onlinezugriff via DOI 1 abstract jats NATIONALLICENCE 856 40 https://doi.org/10.1016/S1010-7940(05)80162-9 text/html Onlinezugriff via DOI NATIONALLICENCE 773 0- European Journal of Cardio-Thoracic Surgery Elsevier Science B.V 9/5(1995-05), 275-282 1010-7940 9:5<275 1995 9 ejcts Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
